Specific implementation mode

In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

As shown in figures 1 to 6, the ISOFIX backing stop structures of the utility model include：Connector 1, gear shaft 2, multiple gear cards Slot 3 and stopping mechanism 4.

Connector 1 is mounted on the pedestal 5 of child safety seat horizontally moveablely, and connector 1 is suitable for and car seat On the connection of ISOFIX interfaces, so that child safety seat is fixed on car seat.

Gear shaft 2 can be installed on connector 1 to vertical or inclination movement, and gear shaft 2 is maintained at fixed bit by spring It sets.

Each gear card slot 3 is successively set on the side of connector 1, and the lower end connection of each gear card slot 3 along horizontal process, The end of gear shaft 2 extends into gear card slot 3, and gear shaft 2 is maintained at the upper end of gear card slot 3 under the action of the spring；Phase Angled transition between adjacent gear card slot 3, to when external force of the gear shaft 2 by horizontal direction, draw on the inclined-plane of gear card slot 3 Lower slide downward is led, to be moved to next gear card slot 3 by a gear card slot 3；When removing the effect to gear shaft 2 When, it is moved to the upper end of gear card slot 3 under the action of the spring.

Since gear shaft 2 is connect with connector 1, when 1 stress of connector moves horizontally, 2 edge of gear shaft is driven Each gear card slot 3 slides.

In actual use, user needs first to pull out connector 1 from pedestal 5, is then inserted into connector 1 In the interface of automotive seat, and when connector 1 is connect with interface, connector 1 can be by reversed active force, gear shaft 2 at this time It is easy slide downward under the effect of external force, makes the retraction of connector 1, can not be successfully so as to cause connector 1 and connect with interface. Stopping mechanism 4 is precisely in order to the structure for solving the above problems and designing.

It is used to lock or unlock gear shaft 2 to stopping mechanism 4, and when stopping mechanism 4 locks gear shaft 2, connector 1 can not 2 slide downward of gear shaft is driven, therefore connector 1 can not be moved forward and backward；When stopping mechanism 4 unlocks gear shaft 2, connector 1 can drive 2 slide downward of gear shaft.

Stopping mechanism 4 includes retaining connecting rod 41 and retaining part 42.Retaining part 42 is rotatably arranged in outermost gear At the card slot 3 of position, retaining part 42 has retaining card slot 420, the sidewalls vertical of retaining card slot 420, when retaining part 42 is in locking bit When setting, retaining card slot 420 and the entrance of gear card slot 3 are arranged side by side, so that gear shaft 2 also enters while entering gear card slot 3 In retaining card slot 420, when external force of the gear shaft 2 by horizontal direction, it can not be skidded off out of retaining card slot 420, to realize The function of 1 retaining of connector, as shown in Figure 5；When retaining part 42 turns to unlocked position, retaining card slot 420 is far from gear card Slot 3 and gear shaft 2, at this time gear shaft 2 can be moved in the horizontal direction under external force with connector 1, as shown in Fig. 6.

Retaining connecting rod 41 coordinates with retaining part 42, and one end of retaining connecting rod 41 extends to the position operated convenient for user, To make retaining part 42 rotate between locked and unlocked positions by operating retaining connecting rod 41.

Stopping mechanism 4 is maintained at latched position by a retaining spring 43, when connector 1 moves outermost to, gear shaft 2 Into in retaining card slot 420, connector 1 can not bounce back at this time, and user can be smoothly by connector 1 and connecing on car seat Mouth connection after the completion of connection, when needing to withdraw connector 1, makes retaining part 42 turn to unlock by operating retaining connecting rod 41 Connector 1 and gear shaft 2 can be returned to suitable position and be removed to retaining connecting rod after connector 1 retracts by position at this time 41 external force, under the action of retaining spring 43, retaining connecting rod 41 and retaining part 42 reset to latched position.

Stopping mechanism 4 further includes button 44, and button 44 is located at the outside of pedestal 5, the end of button 44 and retaining connecting rod 41 Connection drives retaining connecting rod 41 to be subjected to displacement when user's operation button 44, and retaining connecting rod 41 drives retaining part 42 by locking Positioning, which is set, turns to unlocked position.

Preferably, retaining part 42 is installed in rotation on by a shaft 45 in pedestal 5, the rear end of retaining part 42 and retaining Connecting rod 41 connects, and retaining card slot 420 is formed in the front end of retaining part 42, when retaining part 42 is in the locked position, retaining card slot 420 is arranged side by side with the entrance of outermost gear card slot 3；Retaining connecting rod 41 is arranged in pedestal 5 with being vertically movable, and retaining Connecting rod 41 is ensured by retaining spring 43 in latched position, when retaining connecting rod 41 moves down under external force, is driven Retaining part 42 turns to unlocked position namely retaining card slot 420 far from gear card slot 3 and gear shaft 2, and gear shaft 2 is unlocked.

Further, connector 1 includes holder 11, set on the connecting pin 12 of 11 both sides of holder and set on 11 front end of holder Gear axle bed 13.Connecting pin 12 is suitable for connecting with the interface of car seat.Gear axle bed 13 is for installing gear shaft 2.Gear Axle bed 13 has inclined hole.

Two position stop pieces 6 are separately positioned on the both sides of connector 1, and multiple gear card slots 3, gear are formed on each position stop piece 6 The middle part of axis 2 passes through the inclined hole on gear axle bed 13, and both ends extend respectively into the gear card slot 3 on two position stop pieces 6.

The above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to In the utility model range claimed.
